Temporally Arrested Breath Figure

Abstract: Since its original conception as a tool for manufacturing porous materials, the breath figure method (BF) and its variations have been frequently used for the fabrication of numerous micro-and nanopatterned functional surfaces. In classical BF, reliable design of the final pattern has been hindered by the dual role of solvent evaporation to initiate/control the dropwise condensation and induce polymerization, alongside the complex effects of local humidity and temperature influence. Herein, we provide a determ… Show more

“…The idea of arresting flows for reliable design and fabrication of self-organized patterns indeed goes far beyond the specific phenomena and liquids discussed in this Perspective. This burgeoning movement is targeting a broad range of phenomena to develop moldless methodologies for assembling optical components, porous materials, textiles, pharmaceutical particles, and fractal and chaotic structures. This type of approach is potentially applicable to a broad range of liquids from commodity/engineering materials (e.g., thermoplastics/thermosets), to innovative materials such as responsive hydrogels and liquid crystal elastomers, to UV curable solutions, to bioactive materials, to cellulose-based materials, and to ceramics and metals. , Of particular interest to technological applications is that the resolution of fluid-mediated assemblies relies on the physics of fluids, e.g., in contrast with printing, where the resolution of the print directly scales with the size of the deposition nozzle and the accuracy of the hardware directing its motion. Instead, the solids we discussed are smooth down to the limit of continuum mechanics .…”

“…With the gradual formation of nanofibers, the droplets originally occupying the surface or inside of the fibers will be evaporated at the same time, and the polymer will solidify because it cannot be replenished in time to the position occupied by the original droplets, thus forming nanofibers with a special pore structure. 85,86 Lynn et al 87 prepared a porous nanofiber-based network using a hydrophobic polyester (poly-(e-caprolactone) (PCL)) widely applied in biomedicine by electrospinning or blow spinning (Fig. 11(a)).…”

“…We recently described the adapted temporally arrested BF approach to control the BF pore size systematically using photopolymerisation and external cooling. 55 Our main goal in this article is to identify control parameters that allow fabrication of temporally arrested BF patterns of predictable pore diameter and spacing through quantitative characterisation of the reversible phase change process. Although reversibility can be practised to some extent in the evaporation-driven breath figure approaches, 23,56 full reversibility of the condensation process 57 and access to intermediate patterns are only possible in methods that eliminate solvent evaporation and provide active polymerisation.…”
